Class I gloves are subject to EN 420: 2003 + A1: 2009. This standard defines the general design, safety, comfort and efficiency criteria applicable to all gloves and protective sleeves.

Class I gloves are also subject to a marking requirement on the glove and instructions for use in their packaging.

The conditions for obtaining the standard EN 420: 2003 + A1: 2009 are as follows:

• Gloves must offer the highest degree of protection in order to ensure optimal safety for the user.
  

• The seams must not injure the user and must be strong enough not to reduce the performance of the glove.

• The materials must not injure the user.

• The gloves should be neutral pH, ie between 3.5 and 9.5.

• The chromium (VI) content should be less than 3 mg / kg on leather gloves.

• Substances that may cause allergies should be mentioned in the glove instruction leaflet (latex glove specificity).

• If washing instructions are given, the performance of the glove must not be altered by washing.

• Gloves should allow maximum finger mobility (dexterity) depending on the required level of protection.

• The standard also specifies requirements for the transmission and absorption of water vapor.

• Special rules apply for antistatic gloves which must be tested according to EN 1149.

• Use of gloves that are too large may increase the risk of accidents. It is therefore important to choose the right size (see table below).

The instruction manual (UIS) must have the following information:

• The name and address of the representative

• The name and address of the approved laboratory that certified the glove

• The designation of the glove and its size

• The explanation of the marking of the glove and the pictograms of the EN standards tested

• Information on potentially allergenic substances contained in the glove

• Maintenance and storage instructions

• Instructions on usage restrictions

• Warnings concerning mechanical or thermal hazards and / or the health hazards of chemicals

The marking of each glove must have the following information:

• The brand of the glove

• The CE logo

• The pictogram of EN tested standards, which defines the level of performance of the glove

• The size of the glove

• The glove reference
